Tern, Tern Tern - ID Help

Look at the top of the primaries: the white hooks strongly suggest a white
hind edge to the upper primaries meaning Roseate or White-fronted.

I don't do Roseates but the jizz is W-f to me, including the very white look
and the "droop snoot" bill due to the curvature of the upper bill being far
greater than that of the lower (except in the possible Common T second from
right).
